The [GBF,GBWW,HTR] at the end are the inclusion codes. The following codes are used:

HTR / htr
Stands for How To Read a Book, Mortimer Adler's classic on intelligent reading. Works with the code HTR
are included specifically in the list in the back of this book; works with the code htr
are included because a generic reference was made to all of the author's works, or all works of a given type
(such as plays, poems, etc).

GBWW
Stands for Great Books of the Western World, the famous collection published by Encyclopaedia Britannica.
Works with this code are included, in whole or in part, in this collection. I have not yet added listings for works
in the expanded GBWW collection (volumes 55-60).

GBF / GBF(50) / gbf(HS) / etc.
Stands for the Great Books Foundation, an organization devoted to promoting the discussion of the Great
Books by people from all walks of life. Works with this code are included, in whole or in part, in one of the
Foundation's reading lists; GBF indicates a work included in the Adult Reading and Discussion Program;
gbf indicates a work included in one of their various other reading and discussion programs, but not in
the adult program. If the work is included in one or both of the other programs, they will be noted in parentheses -
(50) for the 50th Anniversary reading program, (HS) for the High School reading program

GI
Stands for the Great Ideas Program. Works with this code are mentioned, in whole or in part,
in this collection.

HC
Stands for Harvard Classics, Harvard University's collection of classic works. Works with this code are
included, in whole or in part, in this collection. I have not finished listing these works yet.

Please note that this site is constantly under construction - not all works will be coded, or coded completely. So, a
work might be included in all of the collections/books/lists above, but only have one code, or none. If you note a
discrepancy, please let me know.

On-line version linked.
Only incomplete on-line versions available, and none from Amazon.com
Only incomplete on-line versions available, but can buy through Amazon.com
No on-line version linked, but can buy through Amazon.com
No links to on-line version or to Amazon.com
No links to on-line version or to Amazon.com under that name; work may be known under another name for which on-line and/or Amazon.com links exist.

For an author, the symbol refers to any work. So, an author with five listed works will be marked
if any one of his or her works has an etext linked.

Again, these only refer to the availability of the work through this site. If you know of an online version of a work which
we have few or no etexts linked for, please let me know about it. Also, if you note any discrepancies between the symbols in
an index and the actual listing of the work, please let me know.

"Core" - The Core Reading List is of my own design. Any work which appears in three of these four sets of reading lists is included: Great Books Foundation (includes GBF, GBF-50, and GBF-HS); Britannica (includes GBWW and Great Ideas); How to Read a Book (HTR); and Harvard Classics (HC).

"Major" - All works included in any of the four major reading lists, namely the Great Books Foundation Adult Reading Series (GBF), Britannica's Great Books of the Western World (GBWW), How to Read a Book (HTR), and the Harvard Classics (HC).
